Determination of dynamic stiffness of materials used under floating floors in dwellings

거주공간에서 뜬바닥 구조에 사용하는 동탄성계수 측정방법

This part of specifies the method for determining the dynamic stiffness of resilient materials used under floating floors. Dynamic stiffness is one of the parameters that determine the sound insulation of such floors in dwellings. This part applies to the determination of dynamic stiffness per unit area of resilient materials with smooth surfaces used in a continuous layer under floating floors in dwellings
